Function

BOR1_ARATH Efflux-type boron transporter for xylem loading, responsive of boron translocation from roots to shoots under boron limitation. Under boron excess, BOR1 is transferred from the plasma membrane via the endosomes to the vacuole for degradation. Boron is essential for maintaining the integrity of plants cell walls.^{[1] [2]}
